Description

Technical Field

[0001] The utility model belongs to the technical field of drilling vacuum cleaners, and more specifically relates to a suction cylinder structure of a drilling vacuum cleaner. Background Art

[0002] Drilling is one of the common processes in industrial manufacturing. The drill bit is used to drill the workpiece. The drill bit will generate a lot of debris and dust during drilling, polluting the surrounding environment. Therefore, it is often necessary to install a drilling vacuum cleaner at the drilling site to suck away the waste generated during drilling to keep the operating environment clean.

[0003] The existing vacuum cleaner for drilling holes uses a suction nozzle at one end of the suction cylinder to be placed close to the target drilling position of the workpiece to be processed, and the drill is inserted into the suction cylinder from the other end of the suction cylinder, and then the suction nozzle is extended to the target drilling position to drill a hole. The debris and dust generated during the drilling process fall into the suction cylinder through the suction nozzle and are sucked away by the suction device of the vacuum cleaner for drilling holes. However, the existing suction cylinder structure is a relatively closed space inside during this process. Under the suction of the vacuum cleaner for drilling holes, a vacuum-like state is easily formed inside the suction cylinder, and there is a lack of air flow, which makes it difficult to suck away the debris from the drilling, resulting in low dust collection efficiency and easy residue inside the suction cylinder.
